## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability ecb-interest-rates-3e36e778 -d '<json body>'
```

Example prompt: What are the current ECB interest rates right now? Show me the deposit facility, main refinancing operations, and marginal lending rates, plus the last 10 rate changes.

## When to prefer this

Choose this endpoint when you need official, authoritative ECB policy rates sourced directly from the ECB Data Portal, including the €STR overnight rate and a changelog of recent adjustments. Prefer it over scraping financial news sites or using generic economic data APIs when you need precise ECB-sourced figures with timestamps for the eurozone.

## Known failure modes

- ECB Data Portal unavailable — upstream source outage may return error or stale data
- Invalid history parameter (outside 1–40 range) may return validation error
- No recent rate changes if ECB has been on hold — history array may be shorter than requested

## How this service works

European Central Bank key rates (deposit facility, main refinancing, marginal lending) with the date they took effect, the history of deposit-rate changes in basis points, and the latest €STR overnight rate. Official ECB data.

## Output

A JSON object containing: the current €STR rate with its effective date; the three main ECB policy rates (main refinancing operations, deposit facility, marginal lending facility) each with their 'since' date and rate percentage; the data source attribution; and an array of recent deposit facility rate changes showing date, basis-point change, and resulting deposit rate percentage.
